Imaging Microscope Objectives, Dry - Thorlabs
网页2024年7月5日 — Multiple optical elements, including the microscope objective, tube lens, and eyepieces, together define the magnification of a system. See the Magnification & FOV tab to learn more. Thorlabs offers dry objectives made in house, as well as objectives from Olympus, Nikon, and Mitutoyo.
Camera Lenses - Thorlabs
网页Thorlabs offers a wide variety of C-mount camera lenses for machine vision, including standard prime (fixed) lenses, zoom lenses, high-magnification zoom lenses for macro applications, modular zoom lens components, and bi-telecentric lenses; these lenses are compatible with our CMOS cameras.
Telecentric Lenses Tutorial - Thorlabs
网页2024年8月12日 — Telecentric lenses are designed to have a constant magnification regardless of the object's distance or location in the field of view. This attribute is ideal for many machine vision measurement applications, as measurements of an object's dimensions will be independent of where it is located.
